‣ Engineered a native Android POS application utilizing MVVM architecture and Jetpack Compose for NEXGO terminals, designing responsive layouts tailored to diverse screen sizes and physical inputs ‣ Achieved near-100% transaction reliability in production by systematically addressing edge cases, resolving only one reported transaction flow failure across all active deployments ‣ Drove the development of a custom Android launcher capable of receiving remote MQTT commands, facilitating automated operations such as terminal reboots and OTA updates

‣ Automated data validation workflows through monitoring solutions (PyMongo, boto3, Cron), reducing manual oversight by 10+ hours per week ‣ Designed an OTA update pipeline cutting end-to-end software build and deployment time from 5+ hours per release to a fully automated process ‣ Led end-to-end deployment of React admin portal to consolidate workflows into a single tool, reducing cross-team coordination time by ~80% ‣ Built a geospatial visualization tool with Esri’s ArcGIS JavaScript API, enabling clients to self-serve insights and reducing custom reporting requests by ~50% ‣ Addressed costly yield estimation errors from model misclassifications by developing post-processing filtering algorithms, improving prediction accuracy by 20%+

‣ Optimized computer vision models (SSD MobileNet v1) for real-time inference using PyTorch/TensorRT

‣ Implemented motion tracking algorithm (OpenCV) in Android camera application, reducing server-side processing overhead by 50% ‣ Addressed RTSP video streaming bottlenecks on Android cameras via video encoding optimizations, maintaining target FPS and near-zero frame drops
